Introduction of double stage screw CZPT 
Double phase screw CZPT in the major components with double screw,the compression procedure by the 1st phase screw and CZPT screw by means of grading sequence compression.
Double screw CZPT in addition to uphold twin-screw compressor has the positive aspects of simple composition,versatile installation and higher performance,but also highlights the positive aspects of their own efficient,energy-saving:
one.can lessen the bearing load,increase volume efficiency,
2.in the case of some load procedure,can boost efficlency,energy saving.
Double screw CZPT than twin-screw compressor strength conserving up to fifteen%,every run for 8000 hours a calendar year, Annual financial savings of about two hundred thousand yuan electrical power.
Advantage of two stage screw CZPT 
one. Hierarchical compression to help save compression operate
Via the two-stage sequence method, the CZPT solitary-phase compression process is divided into two compression processes. Such a approach setting can lessen the ratio of every solitary-phase compression process, which can effectively decrease the compression and compression of each stage screw. Essential travel power.
In the method of ideal fuel compression, the sum of the energy essential for one-stage stress transmission and the power necessary for multi-phase compression is equal, but in the genuine compression process, thanks to a collection of elements this sort of as the transmission energy reduction of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the increase of the applied force, the useless energy exceeding the exact same ratio is generated, so the useless energy in the true compression process can be decreased by decreasing the compression ratio of each and every stage, so that the sum of the electrical power essential for multi-stage compression is significantly less than that of solitary-stage compression Necessary energy.
2. The intermediate heat oil cools and decreases the temperature of the gasoline moving into the subsequent phase. All the gas compression procedure is truly the process of the friction amongst the fuel and the transferring parts and being compressed by it.
In the existence of friction, the gasoline will rise in temperature thanks to friction, and there will inevitably be a development of shadow accounts. This component of strength will be introduced in the type of power in the fixed volume of air compression by growing its personal strain.
The temperature increase of the fuel increases the pressure of the gasoline itself during the compression approach and raises the compression ratio. As a result, it is necessary to pay extra electricity to push the gear to shrink the air to the wanted force benefit. Consequently, the two-stage screw compressor is supplied with a coolant injection curtain gadget.
